Maybe I'm just being pessimistic, but I'm skeptical of the idea that we can really stop climate change. If I was in charge of everything, I would instead try to focus our resources on trying to adapt to the changing climate.
It's not a binary "We do or we don't" problem. Obviously climate change has already started and will continue regardless of what we do. But we can still control how bad it gets through things like emission reductions.
That said, I agree that we need to work on adaptation as well, because we're obviously going to have to adapt somewhat because previous generations have already screwed us to some extent.
